Reset maintainer for llwang@infor.org
Reset maintainership for llwang@infor.org due to multiple timeouts and email
address permanent failure. Return all ports to the free pool except
py-numpy, which is taken under the wing of the python@ team.
We thank you for your contribution to the FreeBSD project

-Repocopy devel/libtool15 -> libtool22 and libltdl15 -> libltdl22.
-Update libtool and libltdl to 2.2.6a.
-Remove devel/libtool15 and devel/libltdl15.
-Fix ports build with libtool22/libltdl22.
-Bump ports that depend on libltdl22 due to shared library version change.
-Explain what to do update in the UPDATING.
It has been tested with GNOME2, XFCE4, KDE3, KDE4 and other many wm/desktop
and applications in the runtime.

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.
To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.
To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.
Changes to Mk/*:
- Add runtime detection magic in bsd.port.mk

Mass-conversion to the USE_AUTOTOOLS New World Order. The code present
in bsd.autotools.mk essentially makes this a no-op given that all the
old variables set a USE_AUTOTOOLS_COMPAT variable, which is parsed in
exactly the same way as USE_AUTOTOOLS itself.
Moreover, USE_AUTOTOOLS has already been extensively tested by the GNOME
team -- all GNOME 2.12.x ports use it.
Preliminary documentation can be found at:
http://people.FreeBSD.org/~ade/autotools.txt
which is in the process of being SGMLized before introduction into the
Porters Handbook.
